Life is like Tetris. Your accomplishments disappear and your errors add up.
The goal of Tetris is fit falling blocks of shapes together to prevent them from reaching the top. It moves quickly and requires fast decisions . Each mistake makes it more difficult to succeed.
I used to play this game quite a bit. There was nothing like the frustration of making a few mistakes and seeing the tower of misplaced pieces get closer to the top. It becomes harder to erase the mistakes by fitting pieces together. Yet, it can be done. The different shapes fit together. In life, like Tetris, we work to put the pieces together.
